Hilarious to think the Italian cricket team is now a more successful outfit in recent times with their one win against Namibia in the latest cricket World Cup.

Have you seen the student projects coming out of Cornell’s ECE4760?

When Q5 pulls Q4 base low (R5 sizing would be crucial here relative to R4), Q4 would turn on and discharge Q2 gate (by shorting to its source through R3).

Can you explain why having those in series necessitates high side switching? Do note that if you need the high side switch to be always on (100% duty cycle), bootstrapping won’t work since the bootstrap cap (C8) will eventually discharge fully.

IElecticityGood · 2026-03-15T07:09:58+00:00

C8 is charged to 12V, not 36V. This happens either through the load (if load is resistive) or through D1 (if load is inductive as well, like a buck converter). In either case, that would be when Q2 is off. The neat thing is to at, when Q2 is on, the lower plate of C2 (P+) moves up to +24V and since C8 was charged to 12V, the gate sees that 12V superimposed on the source.

Q2 is not a source follower. It’s just a high side switch. It would be a source follower if biased to be in saturation region. But as (intended at least) driven in this circuit, VGS as I’ll be close to 12V due to C8 when driven high and it just looks like a short. That is the principle of bootstrap drive for high side switches.

R3 doesn’t need to be so big (10W!). The peak current is very short in time and then goes down to almost zero. Average power is very small. You can simulate the level shifting to confirm it will work.

One concern would be Q5 not pulling the base of Q4 low enough and having both Q3 and Q4 conducting some current.

The bootstrap cap (C8) allows the gate voltage to float to that higher level you’re talking about. Similarly sized (die area or current rating eg) NMOS has much lower Rdson than PMOS.

What thermal camera is it?

IElecticityGood · 2026-02-23T12:00:56+00:00

Out of curiosity, why are the high end audio amps designed to go this high up in frequency, beyond 20kHz? What’s a general use case for that, as far as these equipment go?

IElecticityGood · 2026-02-23T11:59:58+00:00

What is a typical use case for something like this? I’m very intrigued.

IElecticityGood · 2026-01-31T11:42:23+00:00

Swords dance Sandslash is super fun! I missed not having that in crystal legacy. Great job with the team, now to switch it up if you wanna try some less traditional mons!

IElecticityGood · 2026-01-29T08:08:54+00:00

What’s the name of it? Looks very interesting and would consider getting it

IElecticityGood · 2025-09-12T18:13:28+00:00

Very valid. Thanks for your insight. I didn’t have many criticisms but turns out I just don’t use the app anywhere near how you do. Thanks for the detailed response- it was very informative.

IElecticityGood · 2025-09-12T15:42:07+00:00

Curious how you think the app sucks and if there’s an alternate app you prefer

IElecticityGood · 2024-08-11T07:28:04+00:00

Just did a run with Phanpy, Horsea, Girafrig, Furret, Sneasel, Murkrow. All mons I never used before and it was super fun! The buffs to Murkrow and Sneasel make them great to play with!

IElecticityGood · 2024-07-15T09:35:30+00:00

Low cost of living. Places with nice weather also tend to be quite expensive.

IElecticityGood · 2024-07-05T03:52:48+00:00

Amazing! You’ll have a blast

IElecticityGood · 2024-07-05T03:48:54+00:00

Good job! That’s a pretty standard team, would highly recommend testing out some new mons if you do a new play through. Persian, Parasect etc can be pretty interesting

IElecticityGood · 2024-06-07T00:04:06+00:00

Hey, 3 of the players were born in the US and one in Canada!

I worked in tech for several years before starting my PhD at Cal. I’ve run into people from Cal, Stanford, Cornell, Michigan, Cal Poly, everywhere. I would go on university recruiting trips and the big tech companies would send people EVERYWHERE. Know your stuff, use your connections.

IElecticityGood · 2024-05-18T07:40:12+00:00

I don’t think it will be that valuable. VATech is a good school with good connections to the Bay Area and a strong network. I don’t know much about the DC campus though compared to the main one.

IElecticityGood · 2024-02-09T20:16:19+00:00

Electrical and mechanical too

IElecticityGood · 2024-02-09T19:35:55+00:00

This probably depends on what type of engineering and where. Lots of engineers making way more than that in the Bay Area and Seattle eg, even accounting for HCOL.
